Shirts you wear open over something
Shirts you wear open over something
Most shirts here are cut loose enough to wear open over a T-shirt, so the chest runs wide and the shoulder drops. Buttoning them up is an option, not the plan.
Black lyocell, draped
Five pieces are black lyocell in one loose size: the pleated band collar shirt, the oversized button up shirt, the long draped shirt with a tie waist, the off center button shirt and the short-sleeved boxy lyocell shirt. Lyocell drapes and feels cool and smooth. The layered longline shirt, 101 cm long, and the hooded shirt jacket take the same idea in cotton. The hooded shirt jacket is the mens overshirt of the group, worn open like a light jacket. More in darkwear.
Cotton and cotton-linen
The Japanese button up shirt is 100% cotton twill in five colours, XS to L. The hanfu shirt and the hanfu jacket are cotton-linen in a traditional Chinese cut, and the hanfu shirt runs XXS to XXL. The tie-front jinbei top comes alone or as a set, with more in jinbei.
Linen and patterned shirts
The Shinu linen V neck shirt is a linen and cotton blend with long sleeves and side slits, XS to 3XL. The patchwork shirt is a short-sleeved plaid in viscose, in black or brown.
Choosing a size
One-size pieces are cut loose to fit most builds: check the chest and length on the product page. Sized shirts carry a chart in centimetres. Wash cold and hang to dry.

Frequently asked questions
What is an overshirt?
A shirt cut loose enough to wear open over a tee, sitting between a shirt and a light jacket. The chest runs wider and the shoulder drops past the bone.
How big do these go?
XXS to XXL across the group: the lyocell and cotton pieces come in one loose size, the Japanese button up shirt in XS to L and the hanfu shirt in XXS to XXL.
Are any of them short-sleeved?
The boxy lyocell shirt and the jinbei top have short sleeves. The rest are long-sleeved.
How do I wash a cotton-linen shirt?
Wash cold. Hang it to dry. Linen creases hard in a dryer and the heat weakens the fibre over time.
